本文介绍了如何在SpringBoot2.1项目中集成Mybatis Generator 1.3.7，从创建Maven Web项目到配置pom.xml、application.properties，再到generatorConfig.xml的设置，详细讲解了每个步骤。通过执行Maven命令，成功生成Mapper和XML文件，然后在MySQL中创建测试表，并创建Controller进行数据返回测试，最终实现应用的正常启动和运行。

SpringBoot2.1 集成 Mybatis Generator 1.3.7#

Idea新建项目如图选择

maven-archetype-webapp:RELEASE

等待 IDEA 自动创建完成，如下图

</generatorConfiguration>

编写 SpringBoot 启动类

在IDEA 中配置 SpringBoot 的启动类

执行 Maven 命令生成自动的 mapper 和 xml 文件

-Dmybatis.generator.overwrite=true mybatis-generator:generate

如下图，文件生成成功

在本地MYSQL 里创建测试表

CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `create_date` datetime DEFAULT CURRENT_TIMESTAMP,
  `user_name` varchar(32) NOT NULL,
  `user_status` varchar(32) DEFAULT NULL,
  `user_height` int(11) DEFAULT '0',
  `user_wright` int(11) DEFAULT '0',
  `user_gender` int(11) DEFAULT '0',
  `user_body_type` varchar(32) DEFAULT 'Unknown',
  `user_hair_color` varchar(32) DEFAULT 'Unknown',
  `user_location` varchar(256) DEFAULT 'Unknown',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

表创建好之后，创建测试 Controller

成功启动应用
